COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 310,152, dated December30, 1884.

Application filed June 16, 1884.

To all whom it may concern:

Be it known that we, JOHN SOHOFIELD and HENRY IV. CARTER, citizens ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inCombination-Tools, which arefully set forth in the followingspecification, reference being had to the accompanying drawings, forminga part hereof, and in which Figure 1 is a plan view of our device as acarpet-stretcher, abutting against a part of a rod provided with a rakeor stop. Fig. 2 is a side elevation of the same without the rod. Fig. 3is a side view of the adjustable rod with stop. Fig. 4 shows the stop orrake Z in perspective. Fig. 5 is a side view of the pawl or dog g,withspring i to raise it from the ratchet f. Fig. 6 is a front, and Fig. 7an end,vie\v of a claw or dog form ing part of our device. Fig. 8 showsin plan the carpet-stretcher used with a dog in front when used as acarpet-stretcher. Fig. 9 is a side view of the dog, showing how it isattached to the pin i.

Like letters of reference indicate like parts.

The object of our invention is to construct a combination tool whichshall form a carpet-stretcher, door-fastener, lifting-jaclgfloorclamp,and other like devices, this being an improvement on John Schofieldsformer Letters Patent No. 201,709. The base a is a channeled casting, inwhich plays a rack, 12, actuated by a pinion, a, turning on a pin, (I.Said pinion has a socket, e, for a lever to work the pinion, said pinionand its socket forming preferably one piece. One or both the upper edgesof the front end of the rack Z) are formed. into ratchet-teeth f,against which works a pawl or detent, 9, having a lever, 71, held uponsaid ratchets by a spring, 2'. The upper or outer end of the rack b isformed into a head, j, and the lower end of the base is beveled at anangle of about forty-five degrees, as shown, and has attached to it by ascrew, k, a foot, 7c. In this form, as now de scribed, our device formsa lifting-jack, &c.

To make a floor-clamp, the foot is is removed, and in its place issecured the toothed blade Z by the screw 70, instead of a hinge, asformerly. This apparatus is then set upon a floor-joist, with its head9' against the floor,

(No model.)

l and the teeth of Z 011 the joist, into which they cut and form astrong hold.

To convert the apparatus into a carpetstretcher, attach the rake Z inplace of thev blade Z, (shown in dotted outline in Fig. 2,) and fasten arake, F, upon the end of the head j,- also put the foot k on, as shown;place the foot L" against the end of a rod or brace reaching to theopposite side of the room, or, preferably, against an adjustable brace,m then catch the teeth of l in the carpet and push the heady outward,and when its motion is completed catch the teeth of the rake Z in thecarpet; they will hold what has been drawn out, and repeat the operationif necessary. The rake Z may also be attached to the brace m,instcad ofthe base a,and work equally well. The rod or brace m is preferablyformed of two sticks which slide upon each other, and are held togetherby two clamps, m, and are adjusted to length by a pin, a, through one ofthe clamps and holes in the sticks.

The dog gis not useful in carpetstretching, and to avoid the necessityof working it a spring, 1'", is put in place of the spring 1 whichthrows it up from the ratchetsf.

For a door-fastener the teeth of the dogl are made round and sharppoints, to prevent injury to carpets.

In place of the rod or to hold the stretcher in its place, a dog isattached to the pin 2" and driven into the floor in front of themachine.

It consists of the spur 0, rod 1.), and hook q.

\Vhat we claim is 1. In combination with the base (1, having inclinedend, screw k rack b, pinion c, and rakes l Z the dog 0 q, substantiallyas specified. 1

2. In combination with the base at, having inclined end, screw 7r, rackb, and pinion c, the dog Z, substantially as specified.

3. In combination'with the base a, having inclined end, screw, k, dog Z,rack b, and pinion c, the dog 9, substantially as specified.

4. In combination with the pinion 0, rack b, and base having inclinedend, the screw is and base In, substantially as specified. JOHNSCHOFIELD.
